Volvo Penta has expanded its marine IMO Tier III range with new D13 solutions, demonstrating the company’s commitment to exceeding today’s best practice while in parallel innovating future technologies.

The range of marine commercial Volvo Penta expands with D13 IMO III solutions for IPS-1200, IPS-1350, D13-900, and D13-1000. Each package exceeds the strict IMO III standards and also offers customers the most compact IMO III solution on the market. 

The upgrade boasts a power output of up to 735 kW for inboard and auxiliary applications and is approved for E3 and C1 cycles. The reduction in NOx and hydrocarbon (HC) will decrease from currently permitted levels of 5.6 g/kWh down to 2.0 g/kWh. 

The SCR (Selective Catalytic Reduction) system can be installed in either a vertical or horizontal position, thanks to the brand-new seamlessly rotating outlet, which adds to the versatility of this complete solution. 

Volvo Penta D13: outstanding solutions for critical operations 

On the water, the new D13 IMO III solutions mean that high-speed vessels can easily comply with IMO III requirements. Volvo Penta and Norwegian shipyard Måløy Verft have just delivered the first installation of the new Volvo Penta D13-1000 IMO III package: the new Norwegian ambulance boat Rosesol is a 23-meter high-speed fiberglass catamaran with an 8-meter beam, powered by twin Volvo Penta D13-1000 IMO III. Rosesol is capable of speeds of more than 30 knots. The new vessel launched in May 2022 and now services an area on the country’s west coast spanning some 100 nautical miles and more than 200 islands.

Continuous improvements toward sustainability

Based on extensively tested Volvo Group technology, the solution has already proved itself in tough marine conditions, having undergone extensive testing at sea. The system is built to handle high sulfur fuel (up to 1000 ppm) and cope with high back pressure while maintaining engine efficiency and drivability. 

The new Volvo Penta D13 IMO III package upgrade follows the earlier releases of the Volvo Penta D13 offer for marine commercial, D8, and D16 solutions that also meet the stringent IMO III requirements. 

“Our primary focus remains on innovating tomorrow’s premium sustainable marine propulsion solutions, plus we are equally responsible for advancing today’s best practice,” says Johan Inden, president of the Volvo Penta Marine business. “So, in parallel to developing future hybrid and alternative fuel solutions, the new D13 IMO III solutions demonstrate our commitment to continually improving the efficiency and performance of every Volvo Penta product.” 

Compact and flexible

The Volvo Penta IMO Tier III solution is the most compact on the market – making the transition to IMO III compliance simple, both for Volvo Penta IPS (Inboard Performance System) and traditional inboard shaft installations. The compact design means that existing Volvo Penta IPS-powered vessels will be able to fit the system without engine room alterations.
